Around 115 million American adults have prediabetes, and roughly 80 percent of them have no idea. That statistic has driven a lot of product development in metabolic health tech over the past few years, but most of it has stopped at the data layer. Abbott and Berry Street are now trying to close that gap.

The two companies announced an exclusive partnership on September 23, 2026, combining Abbott’s Lingo continuous glucose monitor with Berry Street’s network of registered dietitians. The idea is straightforward: glucose data tells you what’s happening in your body, but a trained clinician helps you figure out what to do about it.

What Lingo does, and who it’s for

Lingo is an over-the-counter CGM designed for adults 18 and older who are not using insulin. It tracks how food, exercise, sleep, and stress affect glucose levels in real time, and feeds that information into a companion app. It is not a diagnostic device and is not intended for managing diabetes. Think of it as a metabolic awareness tool for people who want to understand their bodies before a clinical problem develops.

It’s available at hellolingo.com, Amazon, Walmart, Walgreens, Best Buy, and Publix, and works with both Android and iOS devices.

What the partnership actually offers

Through the new arrangement, Lingo and Berry Street users get access to a more integrated experience. Specifically:

• Registered dietitians trained specifically on Lingo and CGM data interpretation
• Personalized nutrition recommendations tied to an individual’s glucose trends
• Virtual one-to-one appointments, accessible anywhere in the United States
• Berry Street users can purchase Lingo at a 15 percent discount on four-week plans
• Lingo users are directed to Berry Street sign-up through the Lingo website and email

Berry Street is in-network with more than 1,250 health plans, and the company says 96 percent of its clients pay nothing out of pocket. Coverage still depends on individual plan details, so users will need to verify their own benefits.

The clinical case for combining data with human expertise

This is not just a marketing pairing. Research published in the American Journal of Clinical Nutrition has shown that registered dietitian-led nutrition therapy can improve glucose control, weight, cholesterol, and other cardiometabolic markers, including in people with prediabetes. The data is solid enough that this kind of medical nutrition therapy is increasingly covered by insurers, which is precisely what Berry Street has built its business around.

But published evidence on CGM use in non-diabetic populations is still maturing. What we know is that glucose variability matters even below diabetic thresholds, and that personalized feedback can influence behavior more effectively than generic dietary advice. The combination of continuous monitoring and clinician interpretation is a reasonable clinical hypothesis. Real-world outcomes from this partnership will be worth watching.

Why this matters beyond the product announcement

The metabolic health space has been crowded with wearables and apps promising insight without much follow-through. What makes this partnership worth attention is the insurance coverage angle. Berry Street’s ability to bill more than 1,250 health plans substantially lowers the access barrier for dietitian support, and that changes the economics of the whole offering.

For clinicians, it also raises a practical question worth considering: patients who show up with months of CGM data and a dietitian-informed nutrition plan are going to need primary care and specialist teams who know how to work with that information. The tools are getting ahead of clinical workflows in some settings, and that’s a gap worth preparing for.

So far, Lingo is available in the US and the UK. Whether Abbott expands this partnership model to other markets, or builds similar arrangements with other care providers, will say a lot about where the company sees the CGM category heading for the general wellness population.
